1. This is a "house" built by the Femto-ST Institute in Besançon, France in May this year. They used nano-level assembly tools-a focused ion beam, a gas injection system, and a small flexible robot. Using silica as the material, they moved around on the micrometer scale, and finally built a 20 micrometer long house. The structure is tens of thousands of times smaller, with doors, windows, and chimneys, which is breathtaking.
2. "Hear" the color
This is a photo taken by cell biologists Stephen Freeman and Laurence Delacroix at the University of Liege in Belgium. In order to study the maturation and damage of nerve cells, they cultured this mouse inner ear neuron in vitro, and took a fantasy-colored picture by the way.
3. Jupiter storm vortex
The white circular area in the picture is the center of the storm. It can be seen that almost the entire northern hemisphere has been stirred up, and the layers of Jupiter's "ribbons" that were originally distinct are now intertwined in disorder.
4. Seeing this monster in Nikon's small world video competition, we will never think of it as a tapeworm in the same way.
5. This is the last complete image taken by the Cassini spacecraft before it plunged into the atmosphere of Saturn, ending its glorious mission.
